APPARATUS FOR HOISTING AND CONVEYING BOULDERS.

SPECIFICATION forming part of Letters Patent No. 595,713, dated December 21, 1897.

Application filed November 28, 1896- Serial NO- 613.840. (N0 model.)

To all whom it may concern:

Be it known that I, FRANK W. JAcoBs, a citizen of the United States of America, residing at Plymouth, in the county of Cerro Gordo and State of Iowa, have invented a new and useful Portable Machine for Moving Boulders, &c., of which the following is a specification.

My object is to provide a machine specially adapted for lifting boulders and building stone fences and lifting and moving other heavy objects from one place to another.

My invention consists in the arrangement and combination of operative mechanism upon a carriage adapted therefor, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 is a top view of the machine. Fig. 2 is a side elevation showing the tractionwheels removed. Fig. 3 is a perspective view of the machine in position as required in practical use in placing boulders in a stone fence.

Referring to the accompanying drawings, the reference-letter A is used to indicate the front axle of the machine. A tongue may be pivoted thereto in an ordinary way, and an upright A is also pivotally attached thereto by means of a swivel A as shown in Fig. 3, and inclined a slight degree from the vertical in a rearward direction.

The rear axle B is arched and made much longer than the front axle. Hence the machine may be readily backed over the end of a fence or other large objects. A beam B is extended transversely of the machine above said rear axle. Two side beams B are fixed to the end portions of the beam B and extended horizontally forward to the upright A near its central portion, and renforcingbraces B are fixed to the top of said upright A and to the rear corner of the frame to provide a frame that is strong enough to support great weights at its central portion. The combination of the braces 13 with the top of the post A and the rear ends of the beams B and rear corners produces a truss.

G is a Windlass .mounted in suitable bearing-boxes on the top. central portion of the side beams B and extended transversely of the machine-frame at an angle relative to the axle B and beam B and has a large wheel 0 tached to the free end of the chain.

Guide-blocks C are fixed to the side surfaces of the wheel to project beyond the edge thereof and have their edges beveled to serve as ratchet-teeth.

D is a spring-actuated bar slidingly mounted in suitable bearings D on the side beams B with one end normally held in engagement with the side of the wheel 0 to engage the blocks on the sides of the wheel. A lever D fulcrumed to the machine-frame and extended to the front of the machine-frame, may be conveniently grasped to hold the bar from disengagement with the blocks on the wheel while the wheel is in operation.

F is a rope or cable fixed to the Wheel 0 and wound thereupon, and His a chain Wound upon the Windlass, and a grapple H is at- This grapple may be of any ordinary construction adapted to engage irregular-shaped stones.

In practical use the entire device is moved over a field by draft-animals, and by reason of the peculiar shape of the frame the arched rear axle is easily placed in position directly over the stone to be moved and free access to the stone provided on the side opposite from the wheel 0 on account of the inclined position of the winch relative to the rear axle. The. grapple is then secured to the stone in the ordinary way and the beam detached from the'tongue and secured to the stone in the ordinary Way, and the team detached from the tongue and secured to the rope or cable upon the wheel 0 As the draft-animals advance the wheel and its axle are rotated and the stone elevated. The stop device connected with the Wheel secures it in any position in which it may be placed. The draft-animals are then secured to the tongue and the machine moved to the spot where the stone is to bedeposited. The lever D is then operated to release the wheel and winch and the stone lowered to its place by gravity.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent of the United States therefor, is

1. In a machine for moving boulders and the like, the carriage-frame consisting of an arched axle, a straight beam fixed across its top, a short front axle, a post pivotally. connected therewith by means of a swivel-coupling, a swivel-coupling, beams fixed to the post at their front ends and to the ends of the beam on the rear axle to extend horizontally and braces fixed to the top of the post and the rear end corners of the carriage-frame, all arranged and combined for the purposes stated.

2. In a machine for moving boulders and the like, the carriage-frame consisting of an arched axle, a straight beam fixed across its top, a short front axle, a post pivotally connected therewith by means of a swivel-coupling, a swivelcoupling, beams fixed to the post at their front ends and to the ends of the beam on the rear axle to extend horizontally and braces fixed to the top of the post and the rear end corners of the carriage-frame, a Winch in bearings fixed to the horizontal beams to extend at an angle relative to the rear axle and means for operating the Winch, all arranged and combined for the purposes stated.

3. A machine for moving boulders and the like comprising a carriage consisting of a short the rear axle, braces fixed to the top of the pivoted post and the rear corners of the carriage-frame, a winch O mounted on the frame to extend at an angle to the rear axle, a Wheel 0 fixed bl'ocks C on its side faces, a spring actuated bar D in bearings D fixed to the beams 13 to engage the said blocks and a lever for operating said bar, and a rope for operating the winch, all arranged and combined in the manner set forth for the purposes stated.
